The Telephone Girl and the Lady.

D.W. Griffith short intercuts two different stories before mixing them together at the end. The film focuses on a telephone girl who leaves work for her lunch break at the same time as "The Lady" goes to a jewelry store to pick up some priceless jewels. When the telephone girl returns to work she gets a phone call from the house of "The Lady" as a robber has broken in and is trying to steal the jewels.
